You don’t need a water softener to drink tap water with 450–500 ppm TDS which I assume is what you’re asking about? Actually a lot if high mineral bottled water have a TDS of 500 or higher and this is considered healthy. Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform dilution calculations when working with solutions having the following concentration units: parts per billion (ppb), parts per million (ppm), parts per thousand (ppt), and parts per hundred (pph, %). Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm.
